Breast Ductal Infiltrative Adenocarcinoma Metastasis to the Mandible.

Metastatic lesions to the jaws are rare. The oral sites to which metastasis most commonly occur are the jaws, the gingiva, and the tongue. Lower jaw is a more frequent site of metastasis compared to the upper jaw with posterior areas (ramus, body) that are more prone to the deposition of cancerous cells due to presence of hematopoietic bone marrow, subdivision of local blood vessels and reduced velocity of blood flow.

Autophagy suppresses the formation of hepatocyte-derived cancer-initiating ductular progenitor cells in the liver.

Hepatocellular carcinoma (HCC) is driven by repeated rounds of inflammation, leading to fibrosis, cirrhosis, and, ultimately, cancer. A critical step in HCC formation is the transition from fibrosis to cirrhosis, which is associated with a change in the liver parenchyma called ductular reaction. Here, we report a genetically engineered mouse model of HCC driven by loss of macroautophagy and hemizygosity of phosphatase and tensin homolog, which develops HCC involving ductular reaction.

The Number of Platelets in Patient's Blood Influences the Mechanical and Morphological Properties of PRP-Clot and Lysophosphatidic Acid Quantity in PRP.

The objectives of this study were to compare platelet-rich plasma (PRP) from patients with different concentrations of platelets and to assess the influence of these PRP preparations on human osteoblast (hOB) activity. In the literature, growth factors released by activated platelets have been considered responsible for the active role of PRP on bone regeneration but no specific role has been attributed to lysophosphatidic acid (LPA) as a possible effector of biological responses. In this study, patients were grouped into either group A (poor in platelets) or group B (rich in platelets).
